Terra Drone Europe is specialised in aerial photography at low heights with a geometrically calibrated camera. This enables us to obtain all heights of a surveyed terrain. At the location of each extracted height the X and Y coordinates are also measured. In this manner a digital terrain model (DTM) is created. The advantages of a digital terrain model is that it allows for extremely fast and efficient calculations. In this manner the volume of a stockpile can be evaluated relative to a ground level. If two measurements have been made over a period of time the difference in volume can be computed.
The quality of the digital terrain models are extremely high, recent projects have shown that the average error is less than 20mm. The measurement density (point density) can be as high as 100 points per square meter revealing every important detail in the terrain!
In combination with our sister company Deep BV from Amsterdam, Terra Drone can generate terrain models that extend under water.
